DevOps is not considered a technology but is an idea that began to broaden in the year 2009. As of 2021, DevOps has become a mainstream practice in the field of information technology. The agile nature of DevOps has helped it in receiving a broad endorsement in the area of IT. Freshers are looking out for DevOps Certification to uplift their careers and have the edge over others.
While working in an organization and handling big-scale applications, you will have many different teams to handle, which work on various tasks and the diverse architecture of the applications. Generally, there are two teams – developers and operations, respectively.
Team 1: Developers are responsible for writing the code, designing and testing new features, and many other things.
Team 2 – Operations team is responsible for managing servers, scaling security, bandwidth, issues, backups, etc.
Over time, when the operations team is busy checking and handling many different things, the developers keep sending new features that they expect to get rolled out and wish for immediate deployment of updates, but it hardly happens.
This develops a sense of frustration, and a blame game begins between these two teams when another team does not meet the expectations. While both the teams play a crucial role in an organization, there arises a need of establishing, strengthening the relationship between the operations and developers team. And hence DevOps comes into the picture.
Well, no! DevOps is not a tool, neither a programming language nor a software. But, it is a methodology, a mindset, a philosophy. DevOps is nothing but a changed attitude with a combination of technology aiming for better communication, collaboration, and how employees work together – in short, teamwork.
DevOps is needed because it helps bridge the gaps between developers and operators and helps the company release small features in very little time, and incorporate the received feedback. Due to DevOps, there are fewer software failures, and also the lead time between fixes is reduced.
Roles and Responsibilities of a DevOps engineer
An important factor about DevOps engineering that needs to be remembered is that “DevOps” is formed out of business needs to better grasp the cloud infrastructure in a disarranged environment. A DevOps engineer must have deep knowledge and understanding of concepts like integration, version control, testing, and deployment methods. Everything about serverless computing.
The role of a DevOps engineer is to automate the deployment and configuration, help build automated testing, make the consistency of builds, eliminate the primary source of failures, make upgrades and deployments seamless with ease across platforms.
How good is a Career in DevOps?
Many experts predict that DevOps is one such career option that will reach its peak in the coming years and will be prevailing. DevOps has shaped and changed the world of software and has become a focal point. According to a joint study made in 2017, the DevOps market generated almost $2.9 billion, and by 2022, it is expected to reach around $6.6 billion.
With a DevOps certification, you can have a definite career path that will offer flourishing career growth. There are many opportunities in this field as it will be a highly adopted approach in almost all organizations.
What do I need to become a DevOps Engineer?
Sound DevOps engineers must have a hold on the following skills to promote themself as excellent DevOps engineers:
- Soft Skills: So far, we have understood that DevOps engineers connect bridges between different IT teams. And hence, they need to communicate with the other employees and be empathic because they need to understand their culture. Further blending and working on such a process helps in achieving a balance.
- A deep knowledge of the tools, processes, and technologies: As the scope for a DevOps engineer is increasing exponentially, it is giving rise to new tools and software. As of now, the source control version tools such as Bamboo, Jenkins, Infrastructure Automation tools like Puppet and Ansible, Containerization tools such as Cloud Azure, Docker & LXD, Google Cloud, Deployment Automation using tools such as Jenkins and Maven, etc. are the tools that are used widely.
- Should be possessing security training, but need not be an expert: A DevOps engineer must ensure that the developers create such code written stably and securely, which would also help defend the cyber threats. The earlier a threat is detected, the cheaper it gets to fix the issue. And hence, it is preferred to instigate the security and testing checks right from developing a code. Having a DevOps certification will result in having all the prerequisites and give you an edge over other candidates applying for the same position as you are.
- Testing: A DevOps engineer must possess strong testing skills as we know that testing and automation go hand in hand. Testing is needed to ensure that the application is functioning as expected and provides no sudden breakdown. This is a vital area where DevOps experience, as well as expertise, can be noticed.
DevOps expertise is in high demand in recent times. Every job position with “DevOps” as a keyword or title has started to sprout up everywhere. Also, at the same time, even having a “DevOps Engineer” in your resume along with a DevOps certification will shoot up your chances of getting a good job.
Many researchers have also concluded that the DevOps practitioners are among the highest-paid people in information technology and are difficult to fill. A career in DevOps presents promising opportunities for a good career, and many companies have become all set to accept this methodology.
